Four-week family weather project

Start this optional four-week path with your teacher. Use a simulated station; no equipment or home measurements are needed. You can skip it without penalty.

Talk about one reading each week at home or in class. Nothing is collected or sent back. Any notes stay on your paper.

Open the simulated Wokwi temperature and humidity station for the circuit files and step-by-step launch instructions.

Week 1: Meet the simulated station

Open the DHT22 lab below. Predict the temperature, then run the simulation and compare its serial reading with your prediction.

Sample temperatures (°C): 14, 14, 14. Illustrative values; use these if you cannot run the simulator.

Sammy asks

A sensor turns a physical quantity into a number. What does this station measure?

Week 2: Look for variation

Use the Wokwi sensor controls to change temperature. Take three readings with the setting held steady, then change it. Which changes come from your input?

Sample temperatures (°C): 13.8, 14, 14.2. Illustrative values; use these if you cannot run the simulator.

Temperature Terry asks

These sample readings cluster around 14 °C. Does a decimal place prove that a sensor is accurate?

Week 3: Compare conditions

Change the simulated temperature and humidity one at a time. Explain which value changes. Discuss how light or moisture could affect an outdoor station.

Sample temperatures (°C): 14, 16, 18. Illustrative values; use these if you cannot run the simulator.

Light Lucy and Moisture Maya asks

A warmer reading alone cannot tell us how bright or wet a place is. What other sensor would you need?

Week 4: Explain the evidence

Compare the sample sets from all four weeks. Explain sensing, variation and one limit of simulation to someone at home or in class. Keep any notes on paper.

Sample temperatures (°C): 15, 14, 16. Illustrative values; use these if you cannot run the simulator.

Sammy and Privacy Priya asks

What did the station teach you? Who would need to see a reading, and what should stay private?

Class chart sharing awaits approval

Sharing is unavailable pending an approved external consent route. Turning this option on does not send readings. There are no parent accounts, uploads or class records in this activity.
